Plixer FlowPro

The monitoring interface(s) must first be enabled as defined in the hardware appliance or virtual appliance installation instructions.

Next, connect to Plixer FlowPro over SSH, and then use the enable erspan command to configure Plixer FlowPro for ERSPAN.

enable erspan <interface> <ipaddress/cidr> <gateway> <peerIPaddress> - Configures a monitor interface to receive traffic from an ERSPAN/GRE tunnel. This configuration supports all types of GRE tunnels. The following parameters are required:

• <interface> - Monitors the ERSPAN/GRE tunnel traffic. This interface must be one of the monitoring interfaces displayed by the show interfaces command.

• <interface><ipaddress/cidr> - The IP address dedicated to the ERSPAN/GRE tunnel. This IP must be routable from the monitoring interface to the network device configured to send ERSPAN/GRE. Both the IP address and CIDR are required, which must be unique to this interface.

• <interface><gateway> - Used by the monitoring interface to create a route to keep the outgoing traffic from the ERSPAN/GRE tunnel localized to the monitoring interface.

• <interface><peerIPaddress> - The external address of the network device configured to send ERSPAN/GRE. If the device is a VMware VDS, enter the IP address of the VMware host.

Note

Each monitoring interface on the Plixer FlowPro supports only one ERSPAN configuration. Multiple ERSPAN configurations on the same interface, for example mon1, may produce unpredictable results.
